Minimum, Maximum Temperature

The meter indicates the lowest and highest temperature the transmitter has

measured since the last time the value was cleared. The Time Since Event

indicates the elapsed time since that temperature was measured.

Both the Min and Max values can be reset independently. Clicking on Reset

All Temperature Events will reset the Time Since Event clock and sets the

temperature to the currently measured value.

Time Outside Sensor Limits gives the operator/maintenance personnel an

indication of possible misapplication of the transmitter. The Lower and Upper

operate the same. They both include a Time Since 1st Event, Number of

Events, and Total time.

Total Time Above / Below

This is the accumulated time the temperature sensor has been in an over-

temperature condition. This elapsed total time is independent of the number

of events or frequency; it is the total or sum time the transmitter was in this

condition. These values are not resettable.

Time Since 1st Event

The elapsed time since the first over- temperature was detected. This time

can be reset by clicking the Reset Time Since 1st Events button.

Number of Events

This is the number of times the temperature sensor has been in an over-

temperature condition. These values are not resettable.

Reset Time Since 1st Events

Selecting this reset will set the Since 1st Event for both Above Upper Sensor

Limit and Below Lower Sensor Limit to zero.
